Leviathan is a sea serpent which was mentioned six times in the Bible. It can breathe fire. The Leviathan can walk on land, as it has legs, while also being in the ocean. In book of Job, the Leviathan has been described as a fire-breathing crocodile, even though it is, infact, a serpent as mentioned before. It also symbolizes Israel's enemies. In Jewish mythology, Leviathan is a primordial sea serpent. "May it be cursed by those who curse the day, those prepared to rouse Leviathan."
